SANITARY CHAIR.

. I Specification of Letters Patent;

Application filed June 10, 1916. Serial No. 102,917.

To all whom it may concern.

Be it known that I, JOSEPH H. VVEATH- nnrono, a citizen of the United States, residing in Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Sani tary Chairs, of whichthe' following is'a' specification.

My invention relates to sanitary chairs, primarily for the use of small children and is adapted to enable them to be trained to answer the calls of nature Without constant attention from nurse or mother.

The objects of my invention are to make a sanitary chair which can be constructed and sold at a reasonable cost and which will] efficiently assist the mother ornurse in training the infant child to answer the calls of nature at regular intervals, and which will comfortably and safely support the child without constant attention. It is a further object to provide such a chair which may be adapted to the use of the'child as it gets older,'or adjusted-for the use of children of different ages. I accomplish these objects; by making a chairwith a back of deeply curved, substantially semi-cylindrical cross section integral with andcurving smoothly and regularly into a seat,'also of curved cross section which seat terminates in two separated leg supports, the whole adapted to smoothly fit the back and legs of the child and support it comfortably yet securely either in a recumbent or upright position by providing the back and the leg supports with straps or other fasteningsto' hold the child securely yet not tightly in place; and further by supporting the back and seat adjustably in a frame so that the inclination of the back may be changed from substantially a reclining position for the youngest infant to an upright position for an older child.

The detailed way in which these objects are accomplished is more clearly shown in the accompanying drawings in which,

Figure l is a sectional side elevation taken on the center line;

Fig. 2 is a plan view; h

Fig. 3 is an end elevation;

Fig. 4 is a side elevation showing a modified form of side frame, and

Fig. 5 is a detail.

Referring now to the drawings in which the various parts are indicated by letters of reference. The chair consists of a back A together and braced by cross rounds which is of a deeply curved cross section, preferably somewhat more than half of a hollow cylinder, and which may be held in shape-by curved ribs A A Atthe right hand in Fig. 1 of the drawing this back of curved cross section curves forward, forming a seat B, which seat is of similar cross section being in the case shown practically one quarter of a hollow sphere. This seat B is provided with the necessary sanitary opening 0, which may be the usual circular ends. The sides of these leg supports are preferably turned upward to form aideeply curved or semi circular cross section adapt.-

angles to the back sothat in connection withthe backand' the balance of theseat they form a chair member adapted admi- Patented J an. 8, 1918. p

rably to comfortably and safely support a a of fixed or permanent cross section and are in a fixed relation to each other. straps which may be used, if des1red,to

D-D are fasten the child in the chair.

The combined seat and back A-B, which forms a complete member of the sanitary chair, ispreferably supported by a frame in which EE,- are legs braced by cross members or rounds F thus forming two parallel frames which in turn are can r H is a cross round on which the ba rests and is hinged, or pivoted, giw f support but permittin adjustment of the inclination of the back. At the opposite end of the back A, some meansfof adjustably supporting the back on the side frames must beprovided, and for this purpose I show in Figs. 1-2'anl 3, arms Ihinged tothe back A, which arms carry a rod 5 which rests in a rack K, attached to the legsE permitting that end of the backt o, be'raised or lowered to adjust the inclination "of the back andseat member of the chair from a recliningto a sitting position or vice versa. It will, of course, be evident that the eXact detail of the frame is unimportant so long as the seat and back member is firmly supported; and that the form of pivot or hinge isimmaterial so long as it serves the purpose of permitting the adjusting of the back and seat members to various positions. The rack K, too need not be of the identical form shown so long as the combination permits the results outlined. In Fig. at I have shown a slightly different design of frame in which the legs E, are curved around the cross round H as a center, and racks K curved to lit are placed on said legs. A rod L (Fig. 5) may be passed through the holes K in the racks to support the back A. A is a retainer fastened to the rib A, to lock the back against accidental upward movement.

It will further be noted that the seat and back member may be used independently of any frame, and may, in fact, be entirely separate and be supported on the lap of a person or otherwise as desired.

It will also be noted that eliminating the sanitary opening the chair is in itself a useful and comfortable article and it is distinctly understood that while in the drawing I have shown only that form with the opening that I distinctly reserve the right to make this member with a solid seat without opening as though I had separately shown same.

Having now fully described my invention,

what I claim and desire to secure by Letters Patent in the United States is 2- r 1. As a sanitary chair member, a back and an integral seat permanently formed approximately at right angles to each other, said back and seat being each permanently formed of deeply curved cross section and Copies of this patent may be obtained for five cents each, by addressing the Commissioner edges adjacent to said sanitary opening turned upward to form a leg curved cross section, and described.

3. As a sanitary chair member, a back and support of substantially as. shown an integral seat approximately at right angles to each other, said back and seat being each of deeply curved cross section and said seat having an opening therethrough dividing it into two parts, each part terminating in a leg support of deeply curved cross section, and all the parts of said chair me1n her bein ermanentl shaaed and )ermaa a: .l

nently fixed in their relation each to the other.

4. In a sanitary chair member, the co1nbination with a back of deeply curved cross section, of an integral seat divided by a sanitary opening into two parts, each of said parts terminating in a leg support, of curved cross section, bent downward approximately at right angles to said seat, all of said parts being permanently shaped, and permanently fixed in their relation each to the other.

In testimony whereof, I have hereunto subscribed my name.
